It might be interesting to note, the calibration data for the 812S is not identical to that of its bigger brother, the 832S. Hardware might be the same....calibration for writing is not. Suffice to say - it still "works".

Hi ! I looked for some successful flashing of the DVD Writer from LiteOn SOHW812S to be as 832S , I opened this Link http://codeguys.rpc1.org/firmwares.html but I didn't know which file should I download to use .. Can anyone please point me to the right file and tell me how to flash my Writer ? I am very new for that and my DVD Writer is new too , I bought it since 3 days ago , I mean the SOHW812S . Thanks for any help !

Thx emperor for your answer ... But I am still confused I am very new with that .. Do you mean under this text : LiteOn SOHW-832S • Stock VS01 (for use with the OmniPatcher) • Stock VS03 (for use with the OmniPatcher) • Stock VS04 (for use with the OmniPatcher) ?? If yes then which one should I download ? 01 , 02 , 03 or 04 ? If not this links , then which one ? you mean this Link : Sony DRU-700A (rebadged LiteOn SOHW-832S) • Patched VY05 - enabled bitsetting support ???
